Life is dangerous. I'm glad I have AC in the winter and hot water in the winter....and a place to stay out of the rain. I'm happy we use oil. Can you imagine what would happen if 7 billion people had to revert to cooking and heating with wood?
AC in the summer...I mean..
Why would wood smoke be cleaner?
The city of Spokane, located in a broad valley and troubled occasionally by temperature inversions, often on such occasions bans heating with wood stoves, of which there are many in that city, or imposes regulations requiring what is called "clean" burning, which, as I understand the matter, is detectable by the visual density/color of the smoke emitted. This is done for air quality considerations (i.e., human health, livability), not because of the Global Warming Syndrome.
